WATERf-CLOSET CONNECTION.

Specification of Letters Patent.

Patented Oct. 7, 1919.

'Y Application filed January 23, 1919.` vSerial 110.272,730.

j water closet connections in which the bowl and drainage pipe are connected together by a flexible ferrule that will permit of a certain movement of one part `relative to the other part of the connection without damage to or impairment of the integrity of the joint.

It has been found best in connections of this character to provide additional security against damagefrom jolts or jars to the water closet bowl by bolting the base of'` the closet bowl to the floor, or to a flange on the drainage pipe. If an ordinary bolt and nut is used for this purpose, the flexibility of the joint islimited tota-king up movements due to the shrinking of joints and the like and, should the drainage pipe shrink, even the fraction of an inch, or should the floor rise, as is often the case ;V there would be no give to an ordinary bolt and the resulting stress would break the porcelain base of the closet bowl, the bolts, or some part of the connections, y

In the present invention, in order Ato give the necessary elastic-ity to the connection of the closet bowl to the iloor or to the drainage pipe, so that the bowl can move up Vor down or at an angle to the drainage system within certain reasonable limits and without impairment of the joint connection between the closet bowl and the drainage system and without breaking or damaging the bowl or other parts of the closet or connections, I provide a spring-bolt connection between the base flange of the closet howl and the floor or the upper end o-f the drainage pipe, as the case may be, and in which the spring of the spring-bolt will be normally under such compression as will well serve to hold the closet bowl firmly in place and will still have sufficient compressibility to yield further under accidental jars or jolts or relative movement of the closet bowl and the drainage pipe or thel floor, to compensate for such movement and prevent damage to the bowl or pipe or other parts of the closet connections.

In the accompanying drawing, in which I have illustrated the preferred form of my improvement Figure 1 is a vertical sectional View of the lower part of the closet bowl and the upper part of the drainage p ipe of a water closet connection having my improved spring-bolt appliance securing the closet bowl to the drainage pipe n Fig. 2 is a fragmentary view in vertical section of a portion of the connection shown in Fig. 1, on an enlarged scale with the Vspring of the spring-bolt appliance in its partially compressed normal condition.

Fig. 3, is a view similar to Fig. 2, showing the spring of the spring-bolt connection under greater compression thanis shown in Fig. 2, due to relative movement between `the floor and drainage pipe.

Fig. 4, is a view similar to Figs. 2 and 3, `but showing the base of the closet bowl secured to the floor, instead of to a fla-nge on the drainage pipe, the spring of the spring-bolt connection being in'its normal, partially compressed condition.

The water closet bowl is formed with the usual projecting base 2, which rests on the floor 3 and isl connected by the flexible connection 4, with the drainage pipe 5, and the latter is formed with the laterally extending flange 6, which is arranged in a hole 7, in the floor 3, the upper surface of the flange being normally about on a level with the upper surface of the floor.

The projecting base 2, of the closet bowl is formed with vertical holes 8, and in these holes, which are disposed at suitable distance apart around the base, are arranged the hollow bolts 9, each of which has a nut 10, that bears on a plate or washer 11, the covers, the hole 8, and a head 12 that bears against the lower surface of a clamp 13, that has an upturned outer end 14 that bears against the lower surface of the closet Vbase portion 2, and an inner end that bears 19 is carried on the bolt 16 and this washer rests on top of the hollow bolt 9, and between this washer and the nut 18, is arranged a strong helical spring 20, that is normally maintained in a partially compressed condition and, while in such condition serving to keep the closet bowl and the drainage pipe in proper relative position and the closet bowl in proper position on the floor 3, it being understood that there are as many of the bolts 16, as there are of the hollow bolts 9, and that, consequently, the bowl and drainage pipe will be Secured together at various points around the base of the closet bowl.

The normal relative positions of the closet bowl, the floor and the upper end of the drainage pipe are shown in Figs. 1, 2 and 4, while in Fig. 3 I have illustrated the relative positions these elements may assume by the shrinking or lowering o'f the drainage pipe or the rising of the floor, it being noted that the spring 20, under the last named conditions, is compressed to a greater degree than in the normal position of parts illustrated in Figs. 1, 2 and 4.

In the form illustrated in F ig'. 4, the drainage pipe 5, is devoid of the flange 6, while the spring-bolt (designated in this figure by the numeral 16') is in the forni oi a screw bolt that screws directly into the floor 3, the construction of parts being otherwise the same as shown in Figs. 1, 2 and 3.

I claim:

1. In a water closet connection, the combination with a closet bowl having a projecting base with holes therein and a drainage pipe having a laterally projecting flange, said bowl and said pipe being' eXibly connected together, of hollow bolts arranged in the holes in said base and fitting loosely in said holes, headed bolts extending through the flange of the drainage pipe and through said hollow bolts, nuts carried by said headed bolts and springs arranged on the headedfbolts between said nuts and the upper ends of said hollow bolts.

2. In a water closet connection, the combination with a closet bowl having a projecting base with holes therein and a drainage pipe having a laterally projecting iiange having holes corresponding in position with the holes in said base, said bowl and said pipe being exibly connected together, of headed bolts extending through the holes in the base and the flange, a nut carried by the upper end of each said bolt, and a spring arranged between the said nut and the upper surface of said base.

3. In a water closet connection, the combination with a closet bowl having a laterally projecting base and a drainage pipe flexibly connected with the said bowl, of spring-bolts extending through said base and connected to the drainage pipe and adapted to maintain the bowl and drainage pipe normally in Xed relative positions, while permitting relative movement thereof under abnormal relative movements;

4. In water closet connections, the combination with a closet bowl having a projecting base and screwing into the floor below said base and a drainage pipe connected to the bowl, of bolts passing through the said base, nuts carried on the upper ends of said bolts, and springs carried by said bolts below said nuts and adapted to allow the base to move vertically while the bolts vremain stationary.

In testimony whereof I have aXed my signature. Y
